Google Calendar (CL2)

CL2 makes it easy — even effortless — to keep track of all the events in your life and compare them to what your friends and family have going on in theirs. We’ve designed a calendar that works for you — helping you add events from email, friends, and other public calendars — so you don’t have to spend all your time maintaining your schedule. CL2 even helps you discover new events you might be interested in. We think it’s a great tool for managing your daily schedule, keeping track of what everyone in your family is doing, organizing events for a club or team, or creating public events that you can promote to the world.
